4New.v York, have inventedla new and lmproved Steering Gear, of which the followin is a description.. j

y invention relates to a marine steering gear and more particularly is intended for embodiment in the steering gear of motor boats. With the steering gear as usually' cmployed in motor boats, `for example, the cable running from the steering post to the quadrant on the rudder post has ends fastened at different places to parts of the gearing. When a cable because of undue wear at a given point, is weakened or frayed, the cable is discarded#l rlhe general object of my invention is t0 provide a steering'gear in which the cable runs endlessly through the quadrant and through the cableactuating means operated by the steering p'ost and is adapted to be shifted to take the worn portion away from a point `of severe wear and presnt to the wear an unworn portion of the cable, thereby cable.

The means by which the above and other important objects are attained will clearly appear from the description o'f practical embodiments hereinafter given.

Reference is to be had to the accompanying drawings, it being understood that the drawings are merely illustrative of practical examples of the invention.

Referring at first more particularly to the form of the invention shown in Figures 1 to ing post assemblage 26 and the numeral 27 indicates the quadrant on the rudder post 2,8, 29 in Figure 1 indicating the rudder.

. in accordance with my invention the cable ing of the steering wheel 25 is made endless instead of having ends made fast at one point or another about the cock pit in the boat A. Said cable runs inthe illustrated example over sheavesl at the corners of 109 .the cock pit and through fair-leaders 32 or other guides. rllhe numeral 33 indicates a clampfor the adjacent ends of the cable, the clamp being rovided in lieu of splicing wheremen skilled in splicing are not available for the installation of the steering gear. Theequadrant 27 has grooves 34 at the sides, said grooves overlapping adjacent to the rudder post 28 and at the side of the quadrant opposite where the cable departs in opposite directions from the quadrant to I the sheaves 31. From vthe' overlapping 7o -Figure 14 is a view similar to Figure 11 i yet of said holes 46 and grooves 34al adjacent to the rudder post 28 the cable is led to the interior of the quadl rant through holes at each side of the hubl i 1li-cleat 3 for taking upslack. i

The hub 28t has a keeper .bar 27a secured by screws 27b or equivalent means to the quadrant 27 andoverlying the overlapped endsv of the cable 30 to prevent the latter 20 from jumping from the grooves 34.

In Figure 8 isl shown a lanyard 38b employed'inlieu ofthe screw 38 for taking up slack by tensioning the bight 36, said lanyard 38b being passed through 'a thimble 36a' 25 inthe big-ht 36 and tied tothe bracket 39,

The means for actuating -the cable 2O by the turning of the steering post assemblagev 26 consists in the form shown in Figures 1,

11, 12 and 13, of a sprocket wheel `4O turnl 30-ing with the steering wheel turning in a houslng 41 integral with Athe bearin 42 forvthe steering post. The sprocket w eel `meshes with a length .of c a1n413 made up of arcuate links spaced 35 to accommodate between them the cable 30 so tat lthe' cable' extends longitudinally t rough said chain. On the length of chain 43 at each end is a suitable clam 44 to vfirmly secure the chain to the cab e 30 so 4o that upon' a movement of thel chain in re- `sponseto the turning of the sprocket wheel- 40, the cable 30 will also be 'ven movement for turnin the quadrant .2 In the form shown 1n fording aflon itudinal groove inwhich the cable 30a vis le said rack having 'clamps 44 v to secure fitto the cable and the rack meshing withv a 'pinion 40 on the steering'post of q the assemblage 26, there being a housing 4la for the pinion andrack integral with the bearings 42a.r

In the form shown in Figures 17 yto 19 a drum` drive is. employed for actuating the ,v cable/(3Ob),f.there being a peripherally rum .40b,tu1"ning in bear1ngs-af= ordedfby the housing 41 integral with the Ihearing 42h of th steering assemblage.- For' 5 causing thecable 0b to vbe positively moved aoy by the turning of the drum 40", I produce holes 46A extendingA from the peripheral grobves ofthe dumto. annular grooves or depressions 47 inthe-side faces of the` drum and run theeable 'ateach-side through one' 'y from post, said sprocket mil-11o the' prlpherel @abby-uns @e eSSlygrooves of the drum, the arrangement serving to cause the cable to be pos1t1vely held against running movement; the arrangement, however, permits of the cable being A manually moved in the holes 46. With either .of the constructions shovn I11n l o t e 'caused to Vrun a given distance through the l drum' 40?.l The numeral @48 indicates a guard roller the trunnions 49 of which turn .in integral brackets on the housing 41", the cable 30T passing beneath .said roller and the latter serving to prevent the cablev ofthe drum'. l I would state in conclusion that while the illustrated examples constitute practical.

embodiments ofy my invention, I do not limit myself strictly Ato, the mechanical details Y, y 'I herein illustrated, since, manifestly the same can be considerably varied without de artu're from 'the spirit of the' invention as efined in the appended claims.
